DEAR: an extension of traffic engineering for routing and resource management in ad hoc wireless networks

We propose differentiated engineered adaptable routing (DEAR) for quality-of-service (QoS) routing in ad hoc mobile wireless networks. In DEAR, traffic is engineered for both its locations (as in conventional traffic engineering) and its amount according to the proposed demand-engineered QoS routing. Moreover, QoS is provisioned in a differentiated manner through the proposed differentiated QoS routing, and is adaptable to traffic and network conditions through the proposed adaptable QoS routing. DEAR is generally applicable to previous routing paradigms and QoS routing algorithms based on on-demand, table-driven, or localized routing. We also develop DEAR STAR (selective table-driven ad hoc routing) and DEAR POWER (power-aware on-demand wireless embedded routing) to enable QoS-guaranteed and power-aware routing in ad hoc networks by utilizing stationary wireless stations and/or through dynamic maintenance of virtual stationary nodes. Finally, we apply backward learning to QoS routing in ad hoc networks.
